I see two git branches for GCC-5 at https://git.linaro.org 

1. https://git.linaro.org/toolchain/gcc.git/shortlog/refs/heads/gcc-5-branch 

2. https://git.linaro.org/toolchain/gcc.git/shortlog/refs/heads/linaro/gcc-5-branch

What is the difference between these two branches ?

Which branch should be used for development ?

Is it branch (1) refers to GCC upstream branch for GCC5 & branch (2) is linaro version of branch (1).

Please comment.
